Tidewaiter, of course, 'Tidewaiter Customs' is what it says on James' death record, it looks so obvious once one knows what to look for. Wm. Finlay the son was the informant and the district that Cook Street was in was written as Tradeston.
James' date of death came from the 'Ancestry' website's collection called 'UK Royal Hospital Chelsea Admission Books, Registers and Papers, 1702-1980', under the page headed 9th Regiment of Dragoons, it lists his name, an admission date of 22 September 1814, a residence of Glasgow and the comment 'Died 16/1' in the column marked '1864'.
